2007-10-21[PATCH] audit: watching subtreesAl Viro
New kind of audit rule predicates: "object is visible in given subtree". The part that can be sanely implemented, that is. Limitations: * if you have hardlink from outside of tree, you'd better watch it too (or just watch the object itself, obviously) * if you mount something under a watched tree, tell audit that new chunk should be added to watched subtrees * if you umount something in a watched tree and it's still mounted elsewhere, you will get matches on events happening there. New command tells audit to recalculate the trees, trimming such sources of false positives. Note that it's _not_ about path - if something mounted in several places (multiple mount, bindings, different namespaces, etc.), the match does _not_ depend on which one we are using for access.

2007-10-20dm io:ctl use constant struct sizeMilan Broz
Make size of dm_ioctl struct always 312 bytes on all supported architectures. This change retains compatibility with already-compiled code because it uses an embedded offset to locate the payload that follows the structure. On 64-bit architectures there is no change at all; on 32-bit we are increasing the size of dm-ioctl from 308 to 312 bytes. Currently with 32-bit userspace / 64-bit kernel on x86_64 some ioctls (including rename, message) are incorrectly rejected by the comparison against 'param + 1'. This breaks userspace lvrename and multipath 'fail_if_no_path' changes, for example. (BTW Device-mapper uses its own versioning and ignores the ioctl size bits. Only the generic ioctl compat code on mixed arches checks them, and that will continue to accept both sizes for now, but we intend to list 308 as deprecated and eventually remove it.)

2007-10-19NFS: Fix a race in sillyrenameTrond Myklebust
lookup() and sillyrename() can race one another because the sillyrename() completion cannot take the parent directory's inode->i_mutex since the latter may be held by whoever is calling dput(). We therefore have little option but to add extra locking to ensure that nfs_lookup() and nfs_atomic_open() do not race with the sillyrename completion. If somebody has looked up the sillyrenamed file in the meantime, we just transfer the sillydelete information to the new dentry.

2007-10-19Use extended crashkernel command line on ia64Bernhard Walle
This patch adapts IA64 to use the generic parse_crashkernel() function instead of its own parsing for the crashkernel command line. Because the total amount of System RAM must be known when calling this function, efi_memmap_init() is modified to return its accumulated total_memory variable. Also, the crashkernel handling is moved in an own function in arch/ia64/kernel/setup.c to make the code more readable.

2007-10-19Extended crashkernel command lineBernhard Walle
This patch adds a extended crashkernel syntax that makes the value of reserved system RAM dependent on the system RAM itself: crashkernel=<range1>:<size1>[,<range2>:<size2>,...][@offset] range=start-[end] For example: crashkernel=512M-2G:64M,2G-:128M The motivation comes from distributors that configure their crashkernel command line automatically with some configuration tool (YaST, you know ;)). Of course that tool knows the value of System RAM, but if the user removes RAM, then the system becomes unbootable or at least unusable and error handling is very difficult. This series implements this change for i386, x86_64, ia64, ppc64 and sh. That should be all platforms that support kdump in current mainline. I tested all platforms except sh due to the lack of a sh processor. This patch: This is the generic part of the patch. It adds a parse_crashkernel() function in kernel/kexec.c that is called by the architecture specific code that actually reserves the memory. That function takes the whole command line and looks itself for "crashkernel=" in it. If there are multiple occurrences, then the last one is taken. The advantage is that if you have a bootloader like lilo or elilo which allows you to append a command line parameter but not to remove one (like in GRUB), then you can add another crashkernel value for testing at the boot command line and this one overwrites the command line in the configuration then.
